How are lyrical emotions expressed in music? This paper explores the correlation between affect-carrying lyrics and musical features such as beat strength, duration, pitch height, consonance, and mode. Using computer-aided musicology software music21 and the NRC emotion lexicon, we conduct a corpus study on 1,895 folk and popular song lead-sheets encoded as MusicXML. The study reveals that metrical strength and note lengths are highly correlated with affects, while correlations of pitch height, consonance, and mode are in general less significant, at times contradicting previous research. Measurements of minor vs. major chordal context and tonal certainty, however, reveal certain previously unknown differences among emotional states. The paper uses a larger dataset of observations and gives greater values of significance than has appeared in symbolic corpus analysis of emotions in the past, and includes general discussions and directions for future work.

情感绘画：大型铅页语料库中的歌词，情感和音乐关系

音乐中的抒情情感如何表达？本文探讨了影响情感的歌词与音乐特征之间的相关性，例如节拍强度，持续时间，音高，谐音和模式。我们使用计算机辅助的音乐学软件music21和NRC情感词典，对编码为MusicXML的1,895首民谣和流行歌曲主唱进行了语料库研究。研究发现，音高和音符长度与情感高度相关，而音高，辅音和模式的相关性通常不那么重要，有时与先前的研究相矛盾。然而，对次要和主要和弦背景和音调确定性的测量揭示了情绪状态之间某些先前未知的差异。
